The major in Computer Science requires a total of fifteen 4-credit courses, all completed with a grade of C or higher.

CS students are expected to be comfortable with standard high school mathematics as a well as calculus at a level equivalent to completion of CAS MA 123.

The 15 courses required for the major are divided into four groups: A, B, C, and D. Students must take all courses in Group A, at least 2 courses from Group B, at least 2 courses from Group C, and a total of 15 courses from Groups A–D.

Group A: Foundational Courses  

These courses build essential foundations for the study of CS. Students must take all five.

• CAS CS 111 Introduction to Computer Science 1
• CAS CS 112 Introduction to Computer Science 2
• CAS CS 131 Combinatoric Structures
• CAS CS 210 Computer Systems
• CAS CS 330 Introduction to the Analysis of Algorithms

Group B: Formal Tools

These courses provide training in basic algorithms and formal methods. Students must take at least two from this group.

• CAS CS 132 Geometrical Algorithms
• CAS CS 235 Algebraic Algorithms
• CAS CS 237 Probability in Computing

Group C: Central Topics

These courses are more advanced than Groups A and B, and cover broadly important subfields of CS. Students must take at least two from this group.

• CAS CS 320 Concepts of Programming Languages
• CAS CS 332 Elements in the Theory of Computation
• CAS CS 350 Fundamentals of Computing Systems

Group D: Electives

• All CAS CS courses at the 400 and 500 levels

The list of prerequisites or co-requisites for a CS course may contain a CS course “X” with a non-CS alternative “Y.” In such a case, course “Y” may be counted toward the major instead of course “X.”

In special cases, a student, with consent of the instructor, may petition the Undergraduate Director to count courses other than those specified above. Attention is called to the following: GRS CS courses numbered 600 and above; 500-level courses in Mathematics & Statistics (CAS MA); and Computer Engineering courses offered by the College of Engineering (ENG).

CAS CS major credit will not be given for Metropolitan College (MET) courses.
